Well my truck is down. We have had a cross country trip planned for months. A few days before time to leave my truck randomly shut off one day after I cranked it up. Would not restart. I pumped the filter bulb up and it cranked back up. After a few miles it began skipping and stumbling. Almost shut of driving at about 30mph. I got on the throttle and it slowly cleared out. When I got to work I pumped the bulb again and noticed bubbles coming out around the fuel heater fitting in top. Replaced the filter head with a brand new gm one. Along with the rubber fuel lines because they looked brittle and dry rotted. It ran like a champ after. From idle to wot it was smooth. Better than ever. I drove and idled it for hours the 3 days before time to leave for the trip. Never missed a beat. I thought all was well so I decided to drive it on the trip. We got about 4 hours out and stopped for fuel. I left the truck idling while filing up. It loped hard a couple times then cleared up and was fine. By loping I mean it sounded like cycling the key off and on at idle. We continued on for a couple more hours and stopped again for food. This time I shut it off for roughly an hour. When I cranked it back up it loped way worse. To the point of jumping up to 1500 rpm then going so low it shut off. As long as I was on the throttle a little it'd run decent at anything over 1200 rpm. But it was louder than it had been. I decided to turn around and get my dad's lbz since he wasn't going to use it any for a few weeks anyway.
My truck ran fine on the way back. But it had more of a rattle than it used to. Nothing crazy, just a little louder. Like an lb7 vs an lly. Sometimes it idles normal other than being louder. Other times it lopes and shuts down.
Bottom line, I am 1500 miles from the truck. I'll have a v2 I bought from a member on here. When I get home I'll run logs and all that good stuff. Just wanted to get some ideas of what to look for.
Truck is a 2005 lly 143k miles 4" down pipe back exhaust. Diablo preditor set on 100hp. I have put almost 5k miles on this truck since getting it and it has never missed a beat till now. It has always idled smooth and quiet.
Sorry for the long post, I wanted to be as descriptive as possible.
